Underground Infrastructure of Urban Areas : selected and edited papers from the International Conference on Underground Infrastructure of Urban Areas, Wrocław, Poland, 22-24 October 2008

Underground infrastructure (traffic and railway tunnels, water and sewage ducts, garages, and subways) is essential for urbanized areas, as they fulfill an important role in the transportation of people, energy, communication and water. Underground Infrastructure of Urban Areas is a collection of papers on the design, application, and maintenance of underground and subterranean systems, with a focus on geotechnical aspects and town planning issues. The topics covered include: - Gas and potable water pipes; - Underground storage reservoirs; - Urban technical infrastructure and city management; - Drainage system infrastructures; - Micro tunnelling pipelines; - Underground garages; - Material structures; - Road tunnels. Underground Infrastructure of Urban Areas is of interest to academics, designers and builders of underground structures, manufacturers and suppliers of building materials and equipment, and to policy makers involved in managing and maintaining these structures.
